RAIL-JOINT.

SPECIFICATION forming part of Letters Patent No. 493,939, dated March21, 1893.

Application tiled April25,1892. Serial No. 430,459- (No model.)

To wZZ whom it may concern.-

Be it known that I, FRANK MULVILLE, a citizen of the United States,residing in the city and county of Philadelphia, State of Pennsylvania,have invented a new and useful Improvement in Rail-Joints, whichimprovement is fully set forth in the following specification andaccompanying drawings.

My invention consists of a rail joint formed as hereinafter set forthand claimed.

Figure 1 represents a perspective view of a rail joint embodying myinvention. Fig. 2 represents a central longitudinal section thereof.Fig. 3 represents a transverse vertical section thereof.

Similar letters of reference indicate corresponding parts in the severalfigures.

Referring to the drawings:A designates a railroad rail of usualconstruction. B designates cheek pieces which embrace the neck or weband base of the rail. Depending from the outer sides of the cheek piecesand continuous thereof, are vertical plates 0, from which latter thereproject inwardly the horizontal plates D, which are beneath the base ofthe rail. On the inner ends of the horizontal plates D are upwardlyextending tongues E, it being noticed that the said ends are separated,as Will be seen in Fig. 3.

F designates a key which is inserted between the base of the rail andthe horizontal plates D, the same being formed on its sides withdepending tongues G, which enter grooves G in said plates, at the sideof the tongues E, said key being also formed on its underside withgrooves F, at the side of the tongues G, to receive the tongues E.Depending from the center of the key is a tongue H, which enters thespace between the tongues E or inner ends of the plates D.

The operation is as followsz-The cheek pieces are located on the rail,and the key slipped into position between the base of the rail and theunderneath plates D of said check pieces, it being seen that the tonguesG and E engage with each other, and the tongue H enters between the endsof the plates D, by which provision the key controls the cheek pieces,and while holding the latter firmly on the rail, prevents lateral andvertical displacement of the same.

It is evident that when the cheek pieces are to be removed, the key islongitudinally driven or moved out of position, whereby the severaltongues are disengaged, and as the cheek pieces are no longer controlledby the key, they are disconnected from each other and free of the rail.In the key, on the upper face thereof, is a recess J which is locatedbeneath the joint of adjacent rails, thus permitting the said rails tospring when weight of an engine or a car is superimposed thereon.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

1. A rail joint having cheek pieces embracing the sides of the web andthe top of the base of the rail, vertical plates connected with saidpieces having horizontal plates projecting inwardly, and a key having alongitudinal tongue fitting between the inner ends of the saidhorizontal plates, the said inner ends in contact with the key tonguebeing thickened forming bearings for said tongues and hitting in groovesin the underface of the key, said parts being combined substantially asdescribed.

2. A rail joint having cheek pieces with a key therefor, said key havinga recess in its top between the end of adjoining rails, substantially asand for the purpose set forth.
